如果没有互联网连接，无法启动Unity + Firebase

Question

因此，我已将Firebase Unity插件集成到Unity项目中。如果我没有连接到互联网，我遇到了一个问题，Firebase在尝试获取数据库引用时会抛出各种错误。 （Firebase.Database.FirebaseDatabase）database.GetReference（path）上调用以下错误。

01/02/0001 17:46:29 [Error] WebSocket: ws_0 - could not get ip address 
System.Net.Sockets.SocketException: No such host is known 
    at System.Net.Dns.GetHostByName (System.String hostName) [0x00000] in <filename  unknown>:0 
    at System.Net.Dns.GetHostEntry (System.String hostNameOrAddress) [0x00000] in <filename unknown>:0 
    at Firebase.Database.Internal.TubeSock.WebSocket.GetIpAddress (System.String hostName) [0x00000] in <filename unknown>:0 
UnityEngine.Debug:LogError(Object) 
Firebase.FirebaseHandler:LogMessage(LogLevel, String) 
Firebase.Unity.UnityLoggingService:LogMessage(LogLevel, String) 
Firebase.Database.Internal.Logging.DefaultLogger:Error(String, String) 
Firebase.Database.Internal.Logging.DefaultLogger:OnLogMessage(Level, String, String, Int64) 

我该如何避免这种情况？

try 
{ 
    YourCodeToCallFireBaseFunction(); // statements causing exception 
} 
catch(SocketException e1) //Specifically catch **SocketException** 
{ 
    // error handling code 
} 
finally 
{ 
    // statements to be executed 
}
